FreeCAD won't start, even appimage after pySide2 install

Post by drmacro »

I was working through this tutorial: https://wiki.freecadweb.org/Dialog_creation

When I got the part about converting the dialog to a .py file.

The pyside-uic wasn't found:

Code: Select all

pyside-uic mywidget.ui -o mywidget.py
I then issued the following command:

Code: Select all

python3 -m pip install pySide2
Then the pyside-uic command worked.

But, when FC is started:

Code: Select all

During initialization the error "name '_init_pyside_extension' is not defined" occurred in /home/mac/freecad-build/Mod/Arch/InitGui.py
Please look into the log file for further information

It is followed by a LOT more all complaining about PySide2.

The FC is built from source and still builds with no errors.

Any help on fixing this much appreciated.

FreeCAD is having his version of PySide2.

It is referred as PySide, (that is the old name for the QT4 version) for compatibilty reason.

Probably installing PySide2 you have messed up things and now FreeCAD is not finding his internal version correctly.

I could be no more helpful, as When I'm using GUI work I prefer to desgin the interface from scratch, doing some positioning by hand, as in times, I've not ound usefult the "helpers" to design the interface, for simple things, or even for more complicated things, as using python you could "programmatically" create even a whole interface using some "high level" definition.

Code: Select all

("ifi_sides", ("mn", "Box Sides", "mm", 3, 10, 1, 4),
        "Number of sides"),
    ("cbo_type",  ("mn", "Box Type", ("Closed", "Open", "Frame", "With Cover")),
        "Box Type"),
    ("ifd_hei", ("mn", "Box Height", "mm", 20, 800, 0.5, 200),
        "Box Height (along Y axis), for polygonal boxes this value is the " +
        "internal diameter, (apothem * 2)"),
    ("ifd_wid", ("mn", "Box Width", "mm", 20, 800, 0.5, 100),
        "Box Width (along X axis)"),
This is an example, then a 400 lines of code will traverse to this lis and create the appropriate input interface for many fields:

I used the pip to remove the Pyside2.

And reinstalled all the deps.

Then did a make clean and build.

Same issue.

Edit: in fact, I can't even run an appimage, :o

Sorry, I'm usign only AppImage, to avoid such things, all is in the pack and is "isolated" from the working environment, only drawback is the introspection of Python not working as the AppImage is uncompressed in /tmp/something and something is varying on each run.

But I'm told that it is possible to decompress AppImage in a fixed location and then use it as it was compressed (only drawback is that it use more disc space).

Sadly dependencies hell is a real problem, using internal interpreter as when you compile from scratch is source of troubles, as library versions could diverge and some settings could be left over (like some environment variables).

Chances are that the hidden FreeCAD user directory (I've not seen and indication of what OS you are using, maybe my fault)

Said that many developers use a container to develop on it (didn't know how and what is necessary to do such thing, and the drawbacks).

Hope it help.

I updated the title and added more of the crash report to OP.

I do not now what OS you use, but i install all packages only over apt (Debian). Best experience with that.

I think when you install the packages after compiling you must recompile FreeCAD. For compiling PySide (and other Python packages) is no hard dependencies. Test before you recompile if the Draft Workbench works correctly. I also can compile FreeCAD without PySide, but then the Draft Workbench won't work.

Umm...in this case Ubuntu.

I have not only done what you suggest, but have completely removed (complete removal with apt) ALL the FC deps.
Reinstalled all deps, with apt.
Did a "make clean"
Did a cmake
then build

I also removed the pyside2 package I installed that started all this.

At this point starting either the built version, an appimage, or even a different version of FC I get the errors shown in the OP.
FC never gets to the point of "test if Draft Workbench works correctly"...FC does not run it crashes, can't test anything. :(

hui today i got the same / very similar problem with the freecad-daily build..

system information:

Code: Select all

Operating System: Kubuntu 20.04
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8
Kernel Version: 5.4.0-72-generic
OS Type: 64-bit
Processors: 16 × Intel® Core™ i9-9980HK CPU @ 2.40GHz
Memory: 31,2 GiB of RAM
i worked on a freecad / blender script -
and got some 'PySide' not found messages -
so just thought ok - just install PySide2 with pip and iam fine..:

Code: Select all

pip3 install pyside2
only after this i found the FreeCAD PySide wiki page.
so i added this path to my import handling and it worked for my script.
then i wanted to change something in my FreeCAD model and tried to start FreeCAD-Daily:

Code: Select all

so i thought ok - seems there is something getting in chaos with pyside..
lets uninstalled it:

Code: Select all

pip3 uninstall pyside2
and just to be sure restarted my system.
but the same error comes up.
i also installed the stable version:

and if i try to switch to the Part Design Workbench i get

Code: Select all

name '_init_pyside_extension' is not defined
hm so not usable anyway..



does anybody have any idea how to get this back to working?
i thought that the app-image version is fully isolated....
seems that is not really the case.

you have a local installation of shiboken. This will hide the package within the appimage.
